PIPE-CLEANER.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JACOB PFISTER, citizen of the Republic of Switzerland, and residentof Rochelle Park, in the county of Bergen and State of New Jersey, have invented a certain new and useful Pipe-Cleaner, of which the following is a specification.

This invention relates to pipe cleaners.

Tobacco pipes are diflicult to keepclean. Ordinary use causes a deposit to be formed, and attempts to clean out the stem by pushing a cleaning wire into one end are not satisfactory, because if the cleaning wire fits the bowl tightly like a piston, the gummy condensations will be merely propelled en masse toward the bowl of the pipe, while on the other hand, if the cleaner fits loosely like the usual piece of chenille, it can only gather a small portion of he gummy deposlts on its surface, before becoming merely a dist-ributing agent, spreading the deposit over the entire inside surface of the bore, rather than removing it. Thus, the usual practice is to take the pipe to pieces and pass a number of chenille cleaners through the stem from end to end. .But this process is not thorough, because it only removes the softer deposits which are absorbed by the fibrous chenille. Moreover the pushing of a slender and necessarily frail chenille wire through the pipe stem prevents anything but a comparatively loose fitting chenille wire being used and the grasping of the fouled end by the fingers in pulling the cleaner through the stem is an untidy and unpleasant feature of the operation.

The object of the present invention is to provide a pipe cleaner which is simple and cheap to make and absolutely thorough in action, which removes all or substantially all of the gummy deposits at one operation, and which is convenient and satisfactory in its method of use.

lVith these objects in view the invention consists in the improved pipe cleaner as hereinafter set forth.

a piston which will closely fit the bore 3 of the pipe stem and forcibly scrape or through the largest diameter of the ore, thus removing all the gummy deposits, even those which have been more or less hardened. Constructions of this piston may vary but Patented Apr. 1, 1913.

the best constructions will include a spiral 4 formed by curling the chenille of which the cleaner is composed. This spiral will be formed large enough to fit the largest bores of tobacco pipes, and in fact larger bores than are ever used in tobacco pipes. The

spiral, however, has the capacity of drawing down to a smaller diameter, and will exactly accord itself to the particular bore in which it is used.

Constructions embodying the invention will also include an eye 5 formed on the wire body of the pipe cleaner, this eye together with the wire body bein sufiiciently small, so that the cleaner may fie pushedv into any pipe stem with the eye in advance, and the wire body of the cleaner will furthermore belong enough so that the eye can be passed clear through the stem from end to end thereof, without the piston portion entering the stem at all. 1

There is further provided a hook 6 connected to the eye 5 in the use of the device, but which can be disconnected from the eye during the time that the latter is being pushed into the pipe stem as already described. When, however, the wire body of the cleaner has been projected into the pipe stem as far as possible, the eye 5 will be visibe pulled through with great force and strength, and the piston drawn forcibly into and through the stem, to the diameter of which it accords itself, as already described. The advance portion of the piston willseparate all the gummy deposits from thestem,

and the latter are carried forward, the portions of the piston farther back being com-- paratively clean and serving to give a final wiping ofi action to the bore. Accordingly all the deposits are removed in one action of the piston. This is due to the fact that the piston is pulled through the bowl with considerable force which has not been possible so far as I am aware in any construc- :tion heretofore proposed, because heretofore the piston hasrequired to be pushed into-the stem before it can be withdrawn. Any considerable force .cannot be transmitted through'awire by a push. Above all, the deposits are not a ain redistributed over t einterior wall of t ebore, as would be the. case where. the piston is moved back and forth. On the other hand, the iston is.

V drawn out throughthe bowl-and a lfof the deposits are carried with, it, and the same action of having the front. part of the piston followed up by vthe cleanmg action-oi the after P is 'r'eserved'to the completion,

of the action, t at is to say, until the pipe stem is absolutely clean from the mouthpiece clear through to the bowl. Not only are the mmy deposits removed in a solid mass or ody in this way, but the interior of the pipe is prevented from being wi ed-overfby any portions of the piston whic have'been in the least fouled, aswill be the case with the usual vpipe cleaners heretofore used.

" thrownawey after one use: J *The h'ok 6 ispr'eferably nected with -the' eye 5 in which condition The device "is so cheap that a may he normally eontwiste'dfschenille' as alrea y described, the

V chenille-may be made on aknow'n machine so that the fibers are. either longer or denser at one end,'formmgiapiston 2. In this'way' an efiect is obtained substantially similar to that already described. In like manner. the

eye may be formed in 'various ways either by se arating the two wires of the chenille slight y, thus forming a sort of loop as in a read pointed out.

Fig. 1, or bending over the end of the cheways. The gist of the invention consists in .nille wire as shown in Fig. 2 or in other having. a piston with a slenderextension of greater length than the stem of the pipe and having an eye at its forward end 1n which a hook is detachably engaged or adapted to'be'engaged, the stem being adapted to be used as already described, so as to clean'out the pipe from end to end as a1- "W at is claimed is having .a diameter adapted to be pushed eye z A pipecleaner comprising awire body having an eye at one end, both eye and body end first through an ordinary pipe stem, said wire bod further having a piston at the other en the eye and the forward end of the piston being separated by an intervening length greater than the length ofan ordinary ipe stem, and a hook cooperatin with said eye to pull the whole body an v piston through the stem and bowl as and for the purposes set forth.
